Abstract:
A deflection web is provided for use in a keypad assembly. The deflection web comprises a plurality of actuators resiliently coupled together by a flexible membrane. Each actuator of the deflection web corresponds to a key of the keypad assembly, and for each actuator, the flexible membrane comprises a corresponding radially outwardly extending flange whose thickness varies in a direction from the corresponding actuator. In some instances, the thickness of the flange may increase as the flange extends a distance radially outward from its corresponding actuator. A method for creating the deflection web of the keypad assembly and a method for assembling the keypad assembly are also provided.
